McNair Building Design — M&E Consultancy

Sanitaryware and Specialist Drainage

At McNair Building Design (MBD), we design sanitaryware and specialist drainage systems that support safe, reliable and hygienic wastewater management across a wide range of building types. These systems influence fixture selection, pipework routing, trap arrangements, venting, gradients and the integration of mechanical, electrical and architectural elements, making early coordination essential for successful project delivery.

Sanitaryware and specialist drainage systems affect maintenance access, acoustic performance, water quality management and compliance with hygiene and environmental standards. The overview below highlights the essential aspects of these systems, and what they mean for the successful planning and delivery of your project.

Sanitaryware Overview

Sanitaryware systems provide connections for WCs, basins, showers and kitchen appliances. They require coordinated pipework, gradients, venting and access to ensure reliable operation and compliance with hygiene standards.

Typical PHE system elements:

Project impact

Sanitaryware systems influence room layouts, floor build‑ups, structural penetrations and the coordination of drainage with mechanical, electrical and architectural services. They affect acoustic performance, maintenance access and compliance with hygiene and environmental standards.

Specialist Drainage

Specialist drainage systems support kitchens, laboratories, plant areas and commercial operations requiring enhanced waste management. They include grease traps, interceptors, chemical drainage and dedicated pipework arrangements.

Typical elements:

Project impact

Specialist drainage influences equipment placement, riser planning, pipework routing and the integration of drainage with mechanical, electrical and architectural systems. It affects maintenance strategy, compliance with environmental requirements and longterm operational reliability.

Integration with Building Services

Sanitaryware and specialist drainage must integrate cleanly with mechanical, electrical, structural and architectural design.

Coordination requirements:

Effective coordination at this stage directly influences buildability, programme and longterm maintainability.

Construction, Testing and Handover

Sanitaryware and specialist drainage systems require disciplined installation and testing to ensure performance, hygiene and compliance.

Typical construction phase requirements:

A controlled testing and commissioning process ensures safe operation and longterm performance.
